We recommend testing your dog or cat’s urine first thing in the morning. Results are generally more reliable.

For example, nitrite which is an indicator of a bacteria infection may show a negative result if the urine was not in the bladder for at least 4 hours.

Specific gravity, which is the ratio of the weight of urine compared to the weight of an equal amount of water can vary before and after exercise. (This is especially important in comparing test results for your dog).

Testing the same time of day each time you test and recording your results on the results page will give you an easy way to compare any changes that may appear over time.
